Definitions

  • This invention relates generally to apparatus and methods for situating and securing payloads to support structures, and more specifically, to adaptable payload enabling architecture.
  • BACKGROUND OF THE INVENTION Many aspects of modern commercial aircraft are manufactured in accordance with the particular requirements of the aircraft owner. One such aspect is the arrangement of the various components within the cabin of the aircraft, including the galleys, lavatories, passenger seats, cargo containers, section partitions, and other aircraft components. With conventional payload structure design, additional structure within the cabin of the aircraft is typically added as needed to account for larger than average loading caused by heavy monuments (e.g. lavatories, galleys, etc.) set between the floor and ceiling.
  • heavy monuments e.g. lavatories, galleys, etc.
  • FIGURE 1 is a side, partial cross-sectional view of a conventional floor assembly 50 and a payload assembly 52 in accordance with the prior art.
  • FIGURE 2 is a top elevational view of the conventional floor assembly 50 and payload assembly 52 of FIGURE 1.
  • the conventional floor assembly 50 includes a plurality of seat tracks 54 that extend longitudinally along the cabin of the aircraft.
  • the seat tracks 54 are adapted to be coupled to a plurality of seat assemblies or other aircraft components, which may be positioned at desired locations along the seat tracks 54.
  • Supplemental support members 56 are interspersed among the seat tracks 54 and extend beneath one or more of the payload assemblies 52 (FIGURE 2).
  • a plurality of floor panels 58 are disposed between the seat tracks 54 and the supplemental support members 56.
  • sealant 60 is installed in the gap between the floor panel 58 edges and seat track 54 & 56 edges and plugs 62 are installed in the unused, exposed portions of the seat tracks 54 and the supplemental support members 56 in some areas of the cabin.
  • sealing tape (not shown), which is several inches wide, is installed over the sealed gap to minimize leakage between the floor panels 58 and the associated seat tracks 54 and supplemental support members 56.
  • the desired locations of the payload assemblies 52 e.g.
  • galleys, lavatories, etc often do not align with the seat tracks 54, so that the supplemental support members 56 must be added to carry the loads.
  • a payload assembly 52 such as a galley
  • a galley area mat (not shown) must be removed.
  • payloads where the galley is going to be placed must also be removed (setting off another chain reaction of tasks).
  • Sealing tape and sealant around the initial position of the galley must be removed.
  • floor panels around the initial position of the galley must be removed. Sealing and sealing tape around the periphery of each of the floor panels must be removed, and the galley must be disconnected and moved out of the way.
  • old. system interfaces must be removed and terminated (e.g. power, electronics, waste, air, heat, etc.), and new system interfaces at the new galley location must be designed, manufactured, and installed.
  • the galley is then moved to the new location and installed, including connection of system interfaces, manufacture and installation of new floor panels, installation of sealant between the floor panels, installation of sealing tape over all floor panel edges, and installation of a new galley mat.
  • the supplemental support members 56 are typically added over the entire portion of the aircraft cabin known as the flex -zone in which the payload assemblies 52 may be desirably located so that they will not need to be added later when a move is desired.
  • the present invention is directed to apparatus and methods for situating and securing payloads to support structures.
  • Embodiments of apparatus and methods in accordance with the present invention may advantageously reduce the labor and expense associated with manufacturing a support structure in a passenger cabin of an aircraft, and with moving a payload within a cabin, in comparison with prior art apparatus and methods.
  • embodiments of apparatus and methods in accordance with the present invention may reduce the weight of the support structure, thereby reducing the operating costs of the aircraft.
  • an assembly in one embodiment, includes a support structure, a floor assembly, and a payload assembly.
  • the floor assembly includes a plurality of elongated engagement members coupled to the support structure, the engagement members being spaced apart and mostly parallel, each engagement member including an engagement surface.
  • the payload assembly includes a payload component positioned proximate to the floor assembly, and at least one payload support coupled to the payload component and engaged with at least some of the engagement members, the payload support being adapted to transfer loads from the payload component to the floor assembly and being moveable with the payload component relative to the floor assembly.
  • the payload support may be a structured floor panel designed to transfer loads from the payload to the floor structure.
  • the payload support might be an intercostal attached to, or resting under a payload floor panel.
  • the payload support might be the outside edge of a partition. All payload supports transfer loads from the payload component to the aircraft structure directly or indirectly thru floor structure.
  • FIGURE 1 is a side, partial cross-sectional view of a floor support structure and payload assembly in accordance with the prior art
  • FIGURE 2 is a top elevational view of a conventional floor support structure and payload assembly of FIGURE 1 in accordance with the prior art
  • FIGURE 3 is a side, partial cross-sectional view of an adaptable payload assembly in accordance with an embodiment of the present invention
  • FIGURE 4 is a top elevational view of a conventional aircraft floor structure in accordance with an embodiment of the present invention
  • FIGURE 5 is an upper isometric view of an adaptable payload assembly in accordance with an alternate embodiment of the invention
  • FIGURE 6 is a lower isometric view of the payload assembly of FIGURE 5
  • FIGURE 7 is a top elevational view of an engagement member of FIGURE 5
  • FIGURE 8 is a side elevational view of an aircraft in accordance with yet another alternate embodiment of the invention.
  • FIGURE 3 is a side, partial cross-sectional view of a support structure 100 and an adaptable payload assembly 120 in accordance with an embodiment of the present invention.
  • FIGURE 4 is a top elevational view of the support structure 100 and the adaptable payload assembly 120 of FIGURE 3.
  • the support structure 100 includes a plurality of floor panels 106, and a plurality of elongated floor supports 102 disposed beneath the floor panels 106 and extending longitudinally along the cabin of the aircraft.
  • Special support members such as supplemental support members 56 of FIGURE 1
  • supplemental support members 56 of FIGURE 1 for payloads are not needed because the payloads can attach to the basic and stable enabling architecture provided by the seat tracks used for the seats.
  • Small and numerous floor panels are not needed because floor panels no longer "break” on special support members and no longer "break” on seat tracks not needed for payload attachment. Instead, larger floor panels can be used which extend over aforementioned special support members and seat tracks.
  • Each of the floor supports 102 includes an engagement surface 104 (FIGURE 3) that engages a lower surface of one or more of the floor panels 106, as described more fully in co-pending, commonly-owned U.S. Patent Application No. (to be determined) entitled “Non-Protruding Seat Track Apparatus and Methods", filed concurrently herewith on March 29th, 2004 under Attorney Docket No. BING-1-1070, and previously incorporated herein by reference.
  • Each of the floor supports 102 is situated significantly below the top surface of the floor panels 106 (and does not protrude above the top surface), and the engagement surface 104 is engaged against the lower surface of the floor panels 106.
  • the engagement surfaces 104 are approximately "flush" (as defined below) with or recessed below the lower surfaces of the floor panels 106 (and with the payload panel 124).
  • the payload panel 124 is a trim element around and optionally under payload components structured to carry traffic loads (people walking, etc.). If a payload panel is strong enough to beam payload loads to surrounding floor structure, then it is also considered to be the payload support serving a dual role.
  • the engagement surface 104 may engage the lower surface of the floor panels 106 directly or indirectly, as a variety of materials or components may be disposed between the engagement surface 104 and the lower surface of the floor panels 106, including, for example, an insert spacer, a clip-nut, cork, tape, or other materials or components. It will be appreciated that the terms "flush” and “flush with” as used in this patent application when referring to the relationship between members that support floor panels (e.g. the engagement surface 104) and one or more adjacent surfaces (e.g.
  • the lower surfaces of the floor panels 106 should be construed as including “approximately flush” or “nearly flush,” and should not be construed as being limited to a precisely co- planar condition.
  • flush and “flush with” should be understood to include a condition of not significantly protruding above such adjacent surfaces.
  • the engagement surface when the engagement surface is said to be "flush” with another surface, the engagement surface and the other surface need not be precisely co-planar, but rather, may be non-planar to a limited degree as long as a floor panel may extend continuously thereover without creating a tripping hazard or other unacceptable conditions.
  • the term “flush” may include an engagement surface that is up to about 0.2 inches higher than an adjacent surface. In other embodiments, the term “flush” may include an engagement surface that is up to about 0.17 inches higher than an adjacent surface as determined by an amount a floor panel is allowed to bend over uneven surfaces.
  • the term “flush” may include an engagement surface that is up to about 0.04 inches lower than an opposing surface such as the top skin of a floor panel. In further embodiments, a greater amount of non-planarity may be acceptable within the meaning of the term "flush” as used herein.
  • the payload assembly 120 includes a primary component 122 coupled to a payload panel 124.
  • the primary component 122 may be, for example, a galley, a lavatory, a passenger seat, an attendant seat, a crew seat, a closet, a cargo container, a section partition, a fireplace, shelving, a bed or other article of furniture, or any other component that may be located within the aircraft (or other vehicle or structure).
  • embodiments of the present invention may be used to secure dividing devices (or partitions) within the passenger cabin of an aircraft, as generally disclosed, for example, in U.S. Patent No. 5,393,013 issued to Schneider et al., and to secure cargo containers as generally disclosed, for example, in U.S. Patent No. 5,090,639 issued to Miller et al.
  • the payload assembly 120 further includes an intercostal 130 transversely disposed between a pair of adjacent floor supports 102.
  • a plurality of payload attachment assemblies 140 couple the payload panel 124 to the floor supports 102.
  • the floor supports 102 are basic and stable members of the support structure 100.
  • the payload panel 124 may be composed of any material or buildup that meets the requirements of the application.
  • the payload panel 124 may be a composite sandwich panel, a plywood panel, a metal sheet, or any other suitable material or structure.
  • the payload panels 124 may include one or more additional members (e.g. the intercostal 130) that may be added when more load carrying capability is required so that such loads may be transmitted (or beamed) to adjacent basic and stable structure (e.g. the floor supports 102).
  • the support structure 100 having the floor supports 102 that are "flush" with the lower surfaces of the floor panels 106 and with the lower surfaces of the payload panel 124 provide a suitable enabling architecture that allows the payload assembly 120 to be economically relocated to other positions.
  • the payload assembly 120 can be picked up and moved within the passenger cabin of the aircraft by detaching the attachment assemblies 140 from the floor supports 102, moving the payload assembly 120 to a new location, reattaching the attachment assemblies 140 at the new location, and sealing the periphery of the payload panel 124.
  • the intercostal 130 moves with the payload panel 124 to the new location.
  • the payload assembly 124 and components thereof e.g. payload panels, intercostals, etc.
  • Embodiments of apparatus and methods in accordance with the present invention may provide significant advantages over the prior art. For example, because the floor supports are flush with the lower surfaces of the floor panels and the payload panels, these panels are not required to "break" at the locations of the floor supports. This allows the payload assembly to be moved with greater ease and economy in comparison with the prior art.
  • the payload intercostal 130 attaches to basic and stable floor supports 102 and is movable with the payload assembly 120, the amount of support structure that is canied on the aircraft (or other vehicle or structure) may be reduced in comparison with the prior art. More specifically, the need for supplemental support members 56 (FIGURE 1) that exist in the flex -zone areas of the cabin can be eliminated. The labor and expense associated with installation of the supplemental support members 56 is therefore reduced. Also, the unnecessary weight carried aboard the aircraft (or other vehicle or structure) is reduced, and the plugs 62 that must be installed in the unused, exposed portions of the seat tracks 54 are reduced. In addition, the labor and expense associated with moving the payload assembly 120 to a new location within the aircraft is also reduced.
  • the payload assembly 120 includes an intercostal 130 that moves with the payload assembly 120, the labor and expense associated with providing new supports at the new location is reduced or eliminated.
  • the floor panels 106 and the payload panel 124 extend over the engagement surfaces of the floor supports 102 rather than "break" at the seat tracks 54 as shown in FIGURE 1, the number of joints between the floor panels 106, 124 and the supports 102 is reduced. Therefore, the sealing requirements are simplified. More specifically, sealing between unlike materials, like the panels 106, 124 and the supports 102 is eliminated along common edges. Tape is simply applied over the joint between the floor panels 106 and the payload panel 124.
  • FIGURE 5 is an upper isometric view of an adaptable payload assembly 200 in accordance with an alternate embodiment of the invention.
  • FIGURE 6 is a lower isometric view of the adaptable payload assembly 200 of FIGURE 5.
  • the payload assembly 200 includes a primary component 202 coupled to a payload panel 204 and payload support 206 which are, in turn, coupled to a plurality of engagement members 208.
  • FIGURE 7 is a top elevational view of one of the engagement members 208 of FIGURE 5.
  • the engagement member 208 has a plurality of coupling apertures 226 disposed therein.
  • the engagement members 208 may have a variety of different coupling slots, apertures, or other suitable coupling mechanisms, such as the lug and opening coupling slot on existing aircraft (except a non-protruding version) or as described more fully in co-pending, commonly-owned U.S. Patent Application No.
  • a plurality of intercostals 206 are coupled to a bottom surface of the payload panel 204.
  • the intercostals 206 extend transversely between and over adjacent pairs of engagement members 208 of a floor assembly 210.
  • the engagement members 208 may be engaged, as with this example, with support beams 212 of a support frame (e.g. an aircraft airframe).
  • the payload assembly 200 may provide the above- noted advantages of flexibility, adaptability, economy and weight savings in an alternate embodiment of the invention.
  • FIGURE 8 is a side elevational view of an aircraft 800 in accordance with another alternate embodiment of the present invention.
  • the various components and subsystems of the aircraft 800 may be of known construction and, for the sake of brevity, will not be described in detail herein.
  • Embodiments of assemblies 802 for situating and securing payloads to support structures in accordance with the present invention may be employed in one or more desired locations throughout the aircraft 800.
  • the aircraft 800 includes one or more propulsion units 804 coupled to an airframe 803 (not visible) disposed within a fuselage 805, wing assemblies 806 (or other lifting surfaces), a tail assembly 808, a landing assembly 810, a control system 812 (not visible), and a host of other systems and subsystems that enable proper operation of the aircraft 800.
  • the assemblies for situating and securing payloads to support structures in accordance with the present invention are distributed throughout the various portions of the aircraft 800, including, for example, within the cockpit (802b), the first-class section (802c), and the coach or business class section (802a).
  • the aircraft 800 shown in FIGURE 8 is generally representative of a commercial passenger aircraft, including, for example, the 737, 747, 757, 767, 777, and 7E7 models commercially-available from The Boeing Company of Chicago, Illinois, the inventive apparatus and methods disclosed herein may also be employed in virtually any other types of aircraft. More specifically, the teachings of the present invention may be applied to other types and models of passenger aircraft and military aircraft, and any other types of aircraft, including those described, for example, in The Illustrated Encyclopedia of Military Aircraft by Enzo Angelucci, published by Book Sales Publishers, September 2001, and in Jane's All the World's Aircraft published by Jane's Information Group of Coulsdon, Surrey, United Kingdom, which texts are incorporated herein by reference.
